Catatonia is seen in various psychiatric disorders, but also rarely occurs in medical conditions with organic cerebral affection. We present a case of a previously mentally healthy male, who developed catatonia years after a stroke in the right hemisphere. Catatonic symptoms included stupor, mutism, stereotyped movements and repetition of meaningless sounds. The condition responded to benzodiazepine and electroconvulsive therapy. Catatonia should be considered as a differential diagnosis when the described symptoms occur in patients with a known organic cerebral disorder.
